Multifunctionalized Carbon Nanotubes Polymer Composites: Properties and Applications

Abstract

Carbon nanotubes (CNTs) is a rigid rod-like nanoscale material produced from carbon in powder, liquid, or gel form via acid or chemical hydrolysis. Due to its unique and exceptional renewability, biodegradability, mechanical, physicochemical properties, and abundance, the incorporation associated with a small quantity of CNTs to polymeric matrices enhance the mechanical and thermal resistance, and also stability of the latter by several orders of magnitude. Moreover, NCC-derived carbon materials are of no serious threat to the environment, providing further impetus for the development and applications of this green and renewable biomaterial for lightweight and degradable composites. Surface functionalization of CNTs remains the focus of CNTs research in tailoring its properties for dispersion in hydrophilic and hydrophobic media. Through functionalization, the attachment of appropriate chemical functionalities between conjugated sp 2 of CNTs and polymeric matrix is established. It is thus of utmost importance that the tools and protocols for imaging CNTs in a complex matrix and quantify its reinforcement, antimicrobial, stability, hydrophilicity, and biodegradability are be developed.

Factors affecting carbon nanotube fillers towards enhancement of thermal conductivity in polymer nanocomposites: A review

Multi-Walled Carbon Nanotubes-Based Sensors for Strain Sensing Applications

“…Furthermore, nowadays, with the presence of conductive polymers like PEDOT: PSS, the compromise in the electrical conductivity is also reduced to a great extent. Although the quality of the MWCNT composite-based strain sensors is better than the pure ones due to their higher selectivity, the pure ones have other advantages like simpler design, avoidance of any kind of distribution of the nano-fillers in the polymer matrix, and chances of agglomeration [ 99 ].…”

Laser-Assisted Printed Flexible Sensors: A Review

“…For example, while increasing the sensitivity of the sensors, certain attributes like thermodynamic stability becomes worse in SnO2-CuO-based sensors [113]. Some other issues for nanocomposite-based printed sensors that need attention are the non-uniform distribution of the nano-fillers, formation of agglomeration, and non-uniform cutting of the electrodes [114]. Furthermore, there are compatibility issues with the sensors when they are used for healthcare or environmental applications; in certain cases, the biocompatibility of the sensors makes them unsuitable for wearable ubiquitous sensing purposes.…”
